How to Subtract in Excel: A Comprehensive Guide
Introduction
Greetings, readers! Welcome to our comprehensive guide on how to subtract in Excel. Whether you’re a seasoned spreadsheet wizard or just starting out, this article will provide you with everything you need to know to perform subtraction operations effortlessly in Excel.
Section 1: Basic Subtraction
Subtraction Using the Minus Sign (-)
The most straightforward way to subtract in Excel is by using the minus sign (-). To subtract one cell from another, simply enter the minus sign followed by the cell reference. For example, to subtract cell B2 from cell A2, you would enter the following formula in cell C2:
=A2-B2
Subtraction Using Double Hyphens (–)
If you want to subtract a value without changing the value of the cells involved, you can use double hyphens (–). For instance, to subtract 10 from the value in cell A2 without modifying cell A2, you would enter the following formula in cell B2:
=A2--10

Using Other Math Operators
In addition to the minus sign, you can also use other mathematical operators for subtraction. For example, you can use the subtract sign (-), which is similar to the minus sign but will not ignore leading zeros. You can also use the hyphen (-) as a math operator, which will subtract a number from the one following it.
Subtraction with Formulas
You can use formulas to perform multiple subtractions or complex subtraction operations. For instance, to subtract the average of cells A2:A10 from cell B2, you would enter the following formula in cell C2:
=B2-(AVERAGE(A2:A10))
Section 3: Conditional Subtraction
IF Function
The IF function allows you to perform subtraction under specific conditions. For example, to subtract 10 from the value in cell A2 only if cell B2 is greater than 5, you would use the following formula in cell C2:
=IF(B2>5,A2-10,A2)
CHOOSE Function
The CHOOSE function lets you subtract different values based on a specified index. For example, to subtract 10 from cell A2 if the index in cell B2 is 1, or 20 if the index is 2, you would use the following formula in cell C2:
=CHOOSE(B2,A2-10,A2-20)
Section 4: Table of Subtraction Operations
| Operation | Syntax | Description |
|---|---|---|
| Basic Subtraction | =A2-B2 | Subtracts the value in cell B2 from the value in cell A2 |
| Double Hyphen Subtraction | =A2–10 | Subtracts 10 from the value in cell A2 without modifying it |
| Subtraction with Sign | =A2-(-10) | Subtracts 10 from the value in cell A2, ignoring leading zeros |
| Formula Subtraction | =B2-(AVERAGE(A2:A10)) | Subtracts the average of cells A2:A10 from the value in cell B2 |
| Conditional Subtraction with IF | =IF(B2>5,A2-10,A2) | Subtracts 10 from the value in cell A2 if cell B2 is greater than 5 |
| Conditional Subtraction with CHOOSE | =CHOOSE(B2,A2-10,A2-20) | Subtracts 10 from the value in cell A2 if the index in cell B2 is 1, or 20 if the index is 2 |

FAQ about Subtracting in Excel
How do I subtract two numbers in Excel?
- Use the minus sign (-) between the two numbers, e.g.: =A1-B1
How do I subtract a range of cells?
- Use the SUM function with a negative sign, e.g.: =SUM(-A1:A10)
How do I subtract a constant from a range of cells?
- Use the minus sign (-) and the constant, e.g.: =A1:A10 – 5
How do I subtract a cell from every cell in a range?
- Use the negative sign (-) and the cell reference, e.g.: =A1:A10 – $B$1
How do I subtract the value of a cell from the value of another cell and display the result in a third cell?
- Enter the formula =cell1-cell2 into the third cell, e.g.: =A1-B1
How do I subtract percentages in Excel?
- Convert the percentages to decimals before subtracting, e.g.: =A1-B1/100
How do I subtract dates in Excel?
- Excel stores dates as serial numbers, so subtract the earlier date from the later date, e.g.: =B2-A2
How do I subtract time in Excel?
- Excel stores time as a fraction of a day, so subtract the earlier time from the later time, e.g.: =B3-A3
How do I subtract text in Excel?
- Excel cannot subtract text directly, but you can use the CONCATENATE function to join text strings and subtract them as numbers, e.g.: =CONCATENATE(A1, "-") – CONCATENATE(B1, "-")
How do I subtract a column of numbers from another column of numbers?
- Use the formula =column1 – column2, where column1 and column2 are the headers of the columns you want to subtract, e.g.: =ColA – ColB
